UTILIZATION

I use the 3D KRB set to amplify the following keyboards:
- An MP5
- A Motif rack
- A XK1

The piano is connected to the normal stereo input, the rack on the input provided with the option expand (very interesting on the Rodes or vibras) and the organ in front of the mono tube preamp. I do not use any of the effects of internal XK1 except reverb.

Mixing my hand keyboards to the PA via the XLR.

SOUNDS

The bass is amazing for 10 inches, at least very adequate and fairly round for my taste, the stereo is present if properly position the amp, and the party Leslie is very convincing.

If I wanted to quibble, I might regret the absence of a drum for the bass of the organ, but it is impossible to fit in the box, unless you add a floor to the craft.

OVERALL OPINION

The concept of a stereo amplifier plus a clone of Leslie perfectly matches the configuration that I play keyboards on stage, and I guess this is the case for many of us. I am surprised that no manufacturer have thought of earlier. The sound for me, weight is not excessive, the original look but seriously. After two year of use in all kinds of conditions and many miles, not a single failure.

I have some minor criticisms to make, however. This brand is very poorly distributed in Europe, or at least was at the time of my purchase. Since, as I understand it appears in the catalog of a famous Prussian online store, but at a price that is breathtaking.

On the other hand, the speed settings and acceleration time and fall are not easily accessible: you almost entirely remove the amp to achieve them. Fortunately, the factory settings are essentially those of a 144, which suits me perfectly, but it will not necessarily be the case for everyone. It would have been easier to deport these four knobs on the front, although it should not be used once.

In summary, despite these minor caveats, I feel that this amp was designed and built for me. My opinion is necessarily subjective, but I share it.
